So today I swapped back from an 0411 PCM to the stock Black Box PCM that was in my truck originally. It fired up good the first time I started it and then I shut it of and attempted to start it again and since then it won't start and the trouble code P1351 comes up. I know this code is IC Circuit High Voltage. I did some testing of the power in and out of the ICM and so far it all checks out. The engine ran before I did the swap so I doubt it took a coil with it but could be the gremlin. I am just curious to what the experts here think. I'm hoping I didn't fry the PCM. Not really sure how. It also has good fuel pressure.
Thanks.

Well, considering this all involves swapping pins and connectors back over, I"m gonna guess that you messed up a wire somewhere, either in the wrong place or not all the way in the connector. Other than that, good luck!

Thanks for the reply Justin. I went back through the pins again today. All the colors match the correct pin number. Also I had the thing running and it didnt seem terrible like there was a major problem. I'm starting to thing it is the PCM.

The 0411 I had was corrupt and I didnt see the huge advantage when I had it working correctly. I run a stock motor with a few mods on the exhaust and intake. I do plan on doing a 6.0 liter swap when I can find a spare 6.0.

How did that happen? I don't think I've ever heard of anyone managing to corrupt data on one of those. Makes me wonder if whatever killed the 0411 also killed the black box...

The box it self was corrupt before I got it. It was a deal that wasn't worth the hassle for what I do with the truck. I'll stick with the Blackbox until I do a 6.0L Swap. I'm gonna go through and check the wiring along with the crank sensor.
